nit: Update this param name (this isn't really a query, at least in the sense
that the other id is a query id)

[Dan Beam, 2012/10/29 19:17:05]

how is this not a query_id? it's a magically auto-incrementing IPC id just like
the others.

[Dan Beam, 2012/10/29 20:58:29]

btw, this was removed in favor of a bool to show whether we're requesting an
autocomplete or not, so if that sticks around this isn't necessary as a param.

[Ilya Sherman, 2012/10/29 21:27:47]

query_id was probably just not a very good name to begin with; it was originally
the IPC message id for the Query... method, though I guess it's used for more
than that now.
